Question Greenhouse growing in the Pacific NorthWest

I'm moving to the PNW next year and was wondering what is the latest month I can start flowering outside, or better yet, what is the last month a plant can be in flowering?

Lightbulb Search Suggestion

Hi
I Know Of An Excellent Article Submitted In A Cannabis Culture Magazine Where A Grower In The Vancouver Area Grew Year Round Outdoors Using Greenhouse.
Its Circa 1996-97 , If Memory Serves Me Well. Enter " Growing Year Round In Vancouver , By Vansterdam "
I'll Try Find It Before You Do,lol . Have You Read My Signature Link ( 13 Thoughts ) ?

I would think as long as your greenhouse is warm enough you can veg plants and stick them out to bloom all winter until the days get long again. I would think even 8 hours a day of real sun in a greenhouse is better than 12 under an hps yield wise and quality. Good luck brother.

Default Greenhouse photoperiod

I say you will need some lighting to veg plants from about September till April and this doesn't mean HPS it can be smaller cfls or anything that is enough to break up the long nights. The lights need to run about 2 hours in the night to reduce length of consecutive darkness Especially since the NW is extra rainy in the winter , plants won't veg in a greenhouse without lights when they would be flowering outside. Greenhouse is like outdoors as far as photoperiod.

So basically you need to plan on scheduling like you would for outdoor, unless you plan on doing blackcloth to initiate flowering early or lighting to veg. You would see a big difference in quality with something flowered in Dec/Jan compared with what flowers in sept/oct because of differences in light intensity and photoperiod.

Thanks for the replies

The vegging will be done indoors with LED panels.

Lightbulb Speaking of LED

I plan to replace my HPS with something like this for indoor flowering...
504W Vertical LED Grow Light | High Output 1W LED Grow Lights

I have been using 2 of their 126w panels for vegging and flowering for a couple years and have been very happy with the results and have never had any problems with the panels. My estimate is that each panel provides the equivalent of 250w HPS.

Talking Nw grow seasons

Hey, I'm located in Seattle area and I grow indoors and out up here. Colorado said it very well, it's just to wet up here to really kick out top shelf if you push to early with light dep. i run a 24'x48' and a 10x36 hoop, I prefer a April start, and rather than try for 2 runs, I veg em bigger, flip em July 4th or so, light dep them and I usually can see between 4-6lbs a plant..
But as colo said the light dep makes the difference, a later 'natural' finish gets you much more popcorn buds, less 'even' plant finishing, and less trichrome production than the hotter earlier sun. Not to mention more chance of crop loss due to molds with 'wet season' finish. I scrog my outdoors essentially, having 2-4 layers of trellis netting installed as they grow, it helps control height and gives the weight somewhere to lay without snapping all the branches.
I run 4' single lamp t-5 fixtures above each plant in hoop, on timer until the days are long enough for mama nature to take over and keep them in cycle, but this does not translate to much of a power load.. These are just to maintain cycle, while being very narrow and not blocking natural sunlight.
Anyway, I've seen much medicine lost to mold up here, bring a hoophouse when ya come if you want certainty! Lol:

Hhhg if your just doing a standard outdoor no hoop I'd look at first part of June, end of may.
With cold temps and humidity and lack of sun, hard pressed to run em year round without incurring to much cost. Plus I'm a dad, I like to be able to take a break after harvest. And the cancer collective keeps me hopping.

I have 4 UFO 90 watt LEDs, I tried running them in the hoop for veg, but that brilliant purple looking light makes the hoophouse look like a tube that could be seen from mars. My LEDs are relegated to power outages, excellent for keeping plants in veg mode while I have to run generators and need to shut down a few 1k lamps ect
